Abstract

A method of inspecting a negative film in a photographic processing apparatus comprises the steps of detecting with a detector location data arranged at equal intervals on the negative film, electrically comparing the detected location data with equally distanced reference location data having a regularity and assigned to a standard negative film, and automatically stopping the advancing movement of the negative film upon finding a fault in the regularity of the detected location data.
